fscanf

HI!
I am trying to do a homework assignment that is causing much frustration. The assignment is to sort through 4 arrays (emp_id[MAX], wage[MAX], hours[MAX], week_pay[MAX]. Calculate the week_pay and sort in descending order by emp_id. The problem I now have is that the program is not scanning the information. Here is the code I am using....

infile = fopen("a:\\empout.txt", "r");
if (infile = NULL)
{
print error msg
exit(1);
}
input_status = fscanf(infile, "%ld %f %f",&emp_id[index],&wage[index],&hours[index]);
while (input_status != MAX)
{
index = index + 1;
input_status = fscanf(infile, "%ld %f %f",&emp_id[index],&wage[index],&hours[index]);
}
*record_num = index;
fclose(infile);
}

I declared this functin as: void read_record(long *emp_id, float *wage, float*hours, int *record_num);

When I call the function: read_record(emp_id, wage, hours, &record_num);

Is there anything wrong with this code. When I run a watch these variables show the address no problem but nothing changes the info is not being scanned. This program basically crashes everytime. I can't find anything wrong with the code but maybe I'm missing something. Any help would be appreciated.
Thanks

fscanf returns the number of arguments successfully assigned to variables so in your example input_status should end up with a value of 3 each time you use it so if MAX is not 3 your while loop will run forever if it is 3 it won't loop at all. It only returns EOF if an error has occured.

try this:

Code:

---

index = 0;
while(index < MAX)
{
fscanf(infile,"%ld %f %f", emp_num[index],wage[index],hours[index]);
index++;
}

---

You also used the & in front of your array's in the fscanf, no need for them.

Oh, but you do - it's not an array, its an array element, and so you do need an &

fscanf(infile,"%ld %f %f",
&emp_num[index], &wage[index], &hours[index]);
